It can be seen on the video that the guy with the cart is often passed by cars.

From the point of view of Gmaps, surely if one phone can travel at 40mph+ through a street then it's not clogged, even if a whole pack of other phones seem to be stuck at a very low speed?

(The one passing car would have to be connected to Gmaps as well, of course.)

San Francisco is often clogged, with motorcyclists lane splitting and therefore travelling at significantly higher speeds compared to others. I'm sure median speed gives a better approximation of actual thruput than top speed.

Have you ever been in a traffic jam and seen cars taking the shoulder to pass everyone and exit? Google would need to listen to the masses and ignore the few breaking the law.
